Network Equilibrium Models with a Focus on Energy

In this talk, we present complementarity and variational inequality problems to describe equilibrium problems. This class of problems includes optimization via Karush-Kuhn-Tucker (KKT) conditions, Nash-Cournot games, and many other interesting problems in engineering and economics. We highlight both the theory and some recent applications in energy, concentrating on market equilibria for the natural gas and electric power sectors.

Dr. Steven A. Gabriel is  a Full Professor in the Civil and Environmental Engineering Department at the University of Maryland with an additional appointment in the Applied Mathematics, Statistics, and Scientific Computation Program.  In the Civil and Environmental Engineering Dept. he is Group Coordinator for the Civil Systems Program ( and also is a  Faculty Director of the Master of Engineering and Public Policy Program (, a joint degree program between the Engineering and Public Policy Schools.  Dr. Gabriel is also an Adjunct Professor at the Norwegian School of Science and Technology (NTNU) in Trondheim and a Research professor at the German Economic Research Institute (DIW) in Berlin.
Dr. Gabriel has extensive experience in both mathematical modeling as well as algorithm design for optimization and equilibrium (i.e., complementarity) problems in a variety of engineering and economic areas such as energy, the environment, transportation, and telecommunications.  In addition to his academic background, he has over 25 years experience in industry in mathematical modeling and analysis.  He has an M.S. in Operations Research from Stanford University, and an M.A. and Ph.D. in Mathematical Sciences from the Johns Hopkins University.  Prior to joining the University of Maryland in 2000, he was a project manager for energy modeling at ICF Consulting, a postdoctoral researcher at Argonne National Laboratory, an Operations Research Analyst at Arthur D. Little, Inc., a Systems Analyst with Technology Systems, and a Market Analyst for a kerosene heater company.
Professor Gabriel has over 70 publications in refereed journals, conference proceedings, and technical reports.  He has been an expert panelist for the DOE (Energy Information Administration and National Technology Laboratory) in providing guidance on building an international natural gas model as well as evaluation of their fossil energy programs.  Also, he has been a guest researcher at the Energy Research Center of the Netherlands in Amsterdam assisting with building certain aspects of their European natural gas market model.  Lastly, Professor Gabriel works extensively with both Masters and Ph.D. students in modeling and algorithmic design for infrastructure problems.  Dr. Gabriel is a member of the Institute for Operations Research and the Management Sciences (INFORMS), Mathematical Programming Society (MPS), and a Senior member of IEEE.  In addition, he was as Associate Editor for energy at 
Operations Research and is currently the Area Editor for energy forNetworks and Spatial Economics and an Associate Editor for Energy Economics.
